Time travel is the act of traveling from one point in time to another whether traveling to the past from the present or the future without aging. In the Leijiverse, the methods for time travel of the extravagant kind that likely cannot be replicated in real time.
Time travel uses a special time-space displacement that allows the user to travel to a different point in time. These are often used is special devices like the one used on the Mahoroba but the amount of uses differ depending on if it is feasible or not. The most advanced form of time travel however exist in the Rings of Time. This area holds not only the ability to travel through time but also glimpse into possible timelines for a user to view.
